Create DTS packages is in the msdb database. You didn't indicate what database you're trying to give permissions.

If I remember right for SQL Server 2000, even if you're a DB_Owner member, an explicit DENY such as DENY CREATE VIEW would stop the user from doing so. Check to see if that's the case in the database you're working in.

It completed successfully; but the user has been out of office - so I cannot test it yet. It's his domain account and we're not allowed to have his password. Since it's 2000, I cannot use EXECUTE AS, correct?
